MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed March 18, 1918. Serial No. 223,100.

To all whom it may concern Be it known that I, JOHN G. REED, a citizenof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented certain new and usefulImprovements in Music-Leaf Turners, of whichthe following is aspecification.

This invention relates to an improved music leaf turner and has for itsprimary object to provide such a means which may be easily mounted orattached to the body of a piano, organ, or other similar body orstructure, and convenientlyoperated by the player without in any mannerinterfering with the players operation of the instrument.

Another important object of the invention is to provide such a leafturningdevice, for turning the leaves of. sheet or book music which canbe operated by the players foot without removing the foot from theinstruments pedal.

It is also another important object of the invention to provide va musicleaf turning device which may be applied to a piano or organ and thatthe actuating means may be mounted within the structure of the musicalinstrument without interfering with the operation of its mechanicalparts and without marring the artistic beauty of the instrument.

Yet another important object of the in vention is to provide such adevice for turning the music sheets detachable from its actuating meansand may be removed from the piano or organ when not in use.

And it is a further general object of my invention to provide a deviceas above characterized, which is highly serviceable and convenient inpractical use, consists of relatively few parts of simple form, andwhich may, therefore, be applied to pianos, organs, or to other bodiesor structures where the device may be used for a similar purpose at acomparatively small cost.

. With the above and other objects in view, the invention consists inthe novel features of construction, combination and arrangement of partsto be hereinafter more fully described, claimed. and illustrated in theaccompanying drawings, in which: i

F lgure 1 is a front elevation of apiano case and showing the leafturning device applied, i

Fig. 2 is a vertical section view, partly broken away, taken at rightangles to Fig. 1 in the plane of the supporting sleeve for the leafturning pin,

Fig. 3 is a detail perspective view of the sheet turning element and itsassociated p Fig. 4c is a horizontal section on the line H of Fig. 2,

Figs. 5, 6, 7 and 8 are detail perspective views of certain of theparts.

I have in the accompanying drawings shown a piano case for theapplication of my invention, and which I generally designate by thenumeral 5. Itis however, tobe understood, that the device may be mountedin any other structure or bod in an desired manner for a similar use anthat t erefore, the invention is not to be limited by the presentillustration. Referring to the drawings, in detail, 6 indicates anL-shaped lever, preferably of metal. This lever has its long armfulcrumed intermediate its ends at 6 in the frame of the piano case 5,adjacent the pedal 7, and has near its outer end extending at rightangles and in spaced relation to the piano frame, the foot plates 8 and9. The foot plate 9 is off-set as at 9 to extend under the pedal to therelatively opposite side thereof where it terminates in an upstandinglug 9. The plate 8 has a similar terminal lug 8 located at the otherside of the foot pedal.

The L-shaped lever 6 is further provided on the end of its short armwith an upstanding pin 10. A rod 11 is vertically mounted for turningmovements in the straps 12 and has a collar 13 on its upper end toprevent its upward movement. An arm 14 projecting at right angles to therod 11 and secured thereto prevents the downward movement of the rod, 15designates a stop plate fixed to the base of the piano case forengagement by the arm 14 to limit the turning movement of the rod 11 inone direction. The arm 14 has the slot 16 to receive the pin 10. Theupper end of the rod 11 has the laterally projecting rod or finger 17which is provided with an angularl bent downwardly projecting terminal 1Abell crank lever 18 is pivoted to the under side of desk board 19 as at20, and said bell crank lever having the arms 21 and 22 disposed atright angles to each other and each provided with a longitudinal slot 23and 24 respectively. The

slot 23 in the arm 21 slidingly accommodates the terminal 17 of thefinger 17 on the rod 11. A short pin 25 having on its one end, thedownwardly projecting finger 26 and in its other end the central slot orkerf 27. This pin extends through the opening 28 in the desk board 19and is seated for turning movement on the metal strip 29 attached to thedesk board 1.9. This pin is free for turning movement and its finger 26slidingly engages in the slot 24: provided in the arm 22,

In mounting the rod 11 an opening is provided in the keys as shown at30. This permits the rod to turn freely and without interfering with theoperation of the keys. Also to hold the pin 25 in position, anartistic-ally designed guide plate is mounted on the top of the deskboard 19 as shown at 31.

The detachable music rack and sheet turning member includes the sleeveor tube 32 having the arcuate slot 33 in spaced relation to its lowerend. In the tube, free for turning movement, is the rod 3%, said rodbeing provided with an arm 35 extending through the slot 33. Arectangular lug 36 is provided on the lower end of the rod 34: adaptedfor detachable engagement in the slot 27 in the pin On the arm 35 asleeve 4-1 is frictionally engaged and is adapted to be longitudinallyadjusted. Upon this sleeve the sheet receiving clip 37 is pivotallymounted as at 38. This clip may be of any suitable form, but ispreferably so constructed that it will not tightly clamp the music sheetbut permit of the free movement of the sheet through the clip. A secondclip indicated at 39 is also fixed upon the rod or arm 35, and inwardlyof the latter clip. The arm 35 is provided with a pivot joint as shownat 40. I also provide the arms 41 and at one of their ends with supports42 for holding sheet or book music. These arms are pivotally attached attheir other ends to the sleeve or tube 32 as at 43 and adapted to foldparallel with the sleeve or tube.

It will also be seen from the above description that the clip 37 may befolded into parallel relation with the arm 35 and that this clip isfolded at the point 38 into parallelism with the sleeve 32 and thefolded arm 35.

In assembling the music sheet rack and turning arm in operative positionwith the actuating mechanism, the lower end of the sleeve 32 is inserteddownwardly through the central opening in the plate 31 and the squaredlower end of the rod 34 is engaged in the slot or kerf 27 whereby therod 341 and the part 25 are coupled for rotation as a unit. The arms alon the sleeve 32 and the arm 35 carried by the rod 34am then movedoutwardly and downwardly to horizontal positions and the pivoted clip 37raised to a vertical position. By shifting the sleeve 44:

this clip may be adjusted to receive the lower edge of the left handmusic sheetadjacent the outer vertical edge thereof, while the clip 39receives the music sheet at a point adjacent its inner edge. The coversfor the sheet music are preferably seated upon the supports $2 on theouter ends of the pivoted arms 41.

In the operation of my improved sheet turning device as above describedthe player may shift the L-shaped lever 6 to the right or left byengaging the upwardly projecting ends of the foot plates 8 and 9" withthe toe and shifting the L-shaped lever 6 either to the right or left.The movement of said lever in one direction being limited by theengagement of the lever arm 22 with a part of the piano case structure.The movement of the lever 6 in the opposite direction is limited byengagement of the arm 14 with the stop plate 15. Either movement of theL-shaped lever 6 causes a relative movement of the rod 11 which actuatesthe bell crank lever 18 and thereby affects the rotation of the part 25through the co-action of the lever 24 on the finger 26. The rod 3 1being coupled to the part 25 is thus rotated in the sleeve 32 and thearm '35 connected to the lower end of the saidrod is swung from left toright or vice versa, as the case may be, whereby the musicsheet engagedin the clips 37 and 39 is turned.

The device operates very easily and needs only a slight pressure fromthe foot of the player against the projecting ends of the foot plates 8and 9 and thereby shifting the L-shaped lever on its pivot whereby thesheet or leaf turning member is operated as above described. The toeofthe players shoe may be used for this purpose without removing orlifting the foot from the floor by simply pivoting the heel on the pedaland turning the toe to either side thus pressingagainst either of theprojecting foot plates 8 or9 depending upon the direction in which thefoot is turned.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, manner of operation, andseveral advantages of the invention will be clearly and fullyunderstood. It is to be borne in mind, however, that these features ofthe device are susceptible of many mechanical variations and may beembodied in numerous alternative forms. Therefore, while I have shownand described what I at present believe to be the best embodiment of theinvention, it is to be understood that I expressly reserve the privilegeof adapting all such legitimate modifications as maybe freely embodiedwithin the spirit and scope of the invention.

I claim:
